Ive been using these for years. They work well on a Pitts, but they are a bit stiff for cruising type planes.

Yeh, a bit stiff in so far as vibration goes in the Eagle. May look into more of a stock mount

Q: Is this special heavy duty mount set price for one mount or for the complete kit of four?

This product is priced and sold as a set of 4 mounts.

Q: What part numbers do I need to add for the AN7 BOLTS to complete the kit?

The length is determined by the customers application. It is an AN7 diameter bolt, but the builder needs to measure to determine the length required.

Q: Is this the equivalent LORD PN 08-03600?

It is similar to the J-7402-16 but the heavier duty aerobatic version.

Q: What is the length of the spacer included?


Q: Is this a Lord product? Can it be used on an RV-8 with a Dynafocal mounted IO-360?

These are a VIP product and they are commonly used with the dynafocal rings that we sell. We do not have a specific application reference here.

Q: What is an appropriate torque on the bolts when installing these mounts?

The torque settings will differ based on the engine.
